This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The brick to mortar bond strength affects the performance of the joints in brick masonry when subjected to various loading conditions. The flexural bond strength of masonry units can be measured using a bond wrench or a standard test like ASTM E518 beam test. The early bond wrenches were developed in the 1980s in Australian laboratories. In 2011, an Australian bond wrench was manufactured and consequently an ASTM C1072 Bond Wrench was developed in 2012. Further research was done in the field and two more lightweight bond wrenches, i.e. balanced and unbalanced, were built by Indian students at Texas A&M University. Several researchers have performed experiments to study the bias between different bond wrenches. These researches illustrated that no unacceptable bias existed in the flexural strength values calculated using the Indian balanced and unbalanced wrench. However, there existed a bias between American Bond Wrench and Australian Bond wrenches according to research. This thesis aims at understanding the bias between balanced bond wrench developed at Texas A&M University and Standard ASTM E518 beam test method. Also, Indian balanced and unbalanced bond wrench would be referred as TAMU (Texas A&M University) balanced and unbalanced bond wrench in this report. A total of 50 prisms using Portland cement and Texan bricks were built for this experimental research. The prisms were built in two sets and each prism comprised of six bricks with five joints. The mortar used here was 1:1:6 (cement: lime: sand). The samples were cured for a period of 07 days, and all the experiments were carried out under same weather conditions. TAMU balanced bond wrench was used to test the first set of prisms and second set of prisms were tested using standard ASTM E518 beam method. A Student's t-Test analysis was run between the flexural strength values of the TAMU balanced wrench and ASTM E518 method. From the plots, it can be inferred that the mean value of the American standard was low when compared with the mean values of the balanced bond wrench. The plots of ASTM E518 method and TAMU balanced were quite dissimilar. Further research is recommended using the Texas red brick.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The bond strength of the masonry unit is an important characteristic affecting its performance under different loading conditions, including shear and flexural loading. Bond strength of brick masonry is confirmed experimentally using a variety of techniques, including the bond wrench. Four bond wrenches have been built at TAMU over the last five years. In 2010 a lightweight unbalanced and a balanced bond wrench was developed. An Australian Standard Bond Wrench was manufactured in 2011 and in 2012 an ASTM C 1072 Bond Wrench was developed. Numerous researchers have conducted experiments to study the bias between different bond wrenches. These studies illustrated that no unacceptable bias existed in the flexural strength values calculated using the TAMU balanced and unbalanced wrench. However there existed a bias between American Bond Wrench and Australian Bond wrenches according to research. This thesis aims at understanding the bias between Unbalanced Bond Wrench developed at Texas A&M University and Standard ASTM E518 beam test method. This experimental research uses Portland cement and a total of 50 prisms was built in two sets. Each prism comprised of six bricks with five joints, and all the bricks used were Texan bricks. The mortar used here was 1:1:6. The samples were cured for a period of 28 days, and all the experiments were carried out under same weather conditions. TAMU Unbalanced Bond Wrench was used to test the first set of prisms and second set of prisms were tested using standard ASTM E518 beam method. A t-Test analysis was run between the flexural strength values of the TAMU unbalanced wrench and ASTM E518 method. From the plots, it can be inferred that the mean value of the American standard was low when compared with the mean values of the Unbalanced Bond Wrench. The plots of ASTM E518 method and TAMU unbalanced were quite dissimilar. Further research is recommended using the Texas red brick.

This book was released on 2002 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the auspices of ASTM Committee C-01, an inter-laboratory study (ILS) was conducted to determine precision and bias for bond-wrench testing carried out under the requirements of ASTM C 1329-98 ("Standard Specification for Mortar Cement") and ASTM C 1357-98a ("Standard Test Methods for Evaluating Masonry Bond Strength"). The study involved 3 mortars, 15 laboratories and 17 sets of data. Using the statistical analysis procedures of ASTM E 691-99 ("Standard Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test Method") and the computer software developed to carry out those procedures, values of intra-laboratory repeatability, r, and inter-laboratory reproducibility, R, were developed. Normalized repeatability decreases from about 30% of the mean tensile bond strength with the least restricted data subsets, to about 20% of the mean tensile bond strength with the most restricted data subsets. Normalized reproducibility decreases from about 60% of the mean tensile bond strength with the least restricted data subsets, to about 40% of the mean tensile bond strength with the most restricted data subsets. Potential factors contributing to repeatability and reproducibility are discussed.
